DOOR-JAMB SETTER.

SPECIFICATION forming part of Letters Patent No. 481,245, dated August23, 1892. Application filed November 27,1891. Serial No. 413,198. (Nomodel.)

To all whom it may concern:

Be it known that I, JACOB RITTERBECK, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Door-Jamb Setters; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which 1t appertains to make and use the same, reference beinghadto the accompanying drawings, and to letters of reference markedthereon, which form a part of this specification.

The purpose of the present invention is to provide an adjustable frameof such a con struction as to enable a workman to set doorjambs in theirtrue positions with but very little trouble. To this end I have devisedthe frame illustrated in the accompanying drawings, which is providedwith a slide to enable the sides thereof to be adjusted to any width ofdoor-jamb, and which is also provided with a set of leveling devices toenable the workmen to set and secure the jamb properly in the opening inthe wall.

The invention therefore consists of certain novel arrangements andcombinations of parts, such as Will be hereinafter more fully described,and finally embodied in the clauses of the claim.

In the accompanying sheets of drawings is illustrated my door-jambsetter, in which Figure 1 is a view of the door-jamb setter, aroundwhich has been clampeda door-jamb, the sides of which have been formedperfectly square with each other upon the frame, and the entire devicebeing ready for securing in the hole in the wall. Fig. 2 is a verticalsection taken on line 2 2 in Fig. 1, clearly illustrating the manner ofsecuring the door jamb to the setter by means of clamping devices; andFig. 3 is a view similar to that shown in Fig. 1 of the setter adjustedto fit a door-jamb of greater width.

On Sheet 2, Fig. 4, is a full-sized section taken on line l at in Fig.1,clearly illustrating the construction and mode of securing theclamping devices upon the door-jamb setter and its adj usting-plates andscrews adapted to be forced down against the door-jamb.

Fig. 5 is a similar section taken on line 5 5 in Fig. 1, illustratingthe construction of the adjusting or sliding device, and Fig. 6 is asection taken on line 6 6 in said Fig. 1, showing the arrangement of aspirit-level for setting the device level in a horizontal plane; andFig. 7 is a perspective View of a bracket adapted to, be attached to thedoor-jarnb setter and upon which a level can be arranged, asillustrated, to adjust the device in a vertical plane.

Similar letters of reference are employed to indicate correspondingparts in each of the above-described views.

As indicated in said drawings, the doorjamb setter consists of two sidepieces a a, preferably made of hard wood, planed perfectly true, andwhich may be provided at their upper ends with the small angle-irons aa, which are true squares. Projecting from the inner port-ions of saidside pieces a a, near the top and bottom of each piece, are the arms orbraces a a and c a the arms a havinga longitudinal groove a and the arms0. having the correspondingly-raised portion a, (see Fig. 5,) adapted toslide in said groove, or the positions of the groove and raised portionmay be reversed. By this means the two arms or braces a and a can bemade to slide one upon the other.

To the arms a I have secured by means of screws or pins 1) a yoke 12,the side arms 5 of which are made to embrace the sides of the arms orbraces a and can be firmly clamped against the same by means of the adjusting-screws 19 which extend into the longitudinal slots at in the armsa and can be screwed down against the inner surface or in said arms, aswill be clearly evident from Fig. 5. In this manner by slacking thescrews b said arms a and a can be drawn apart and the side pieces a aadjusted to any Width, as shown in Fig. Said arms a may be provided withone or more scales a to enable the quick and exact adjustment of thedevice.

To the side pieces a I have secured any de sirable number of clampingdevices 0 for securing the door-jamb around the setter, as will bereadily seen from said Figs. 1, 2, and 3. Said clamping devices consist,essentially, ofa rod 0', provided on one end with a screwthread 0 Eachrod is passed through a hole in the side pieces a and convenientlysecured therein either by one or more pins or otherwise, and on eachside of said pieces a and arranged on the rod 0 are perforated plates 0'and 0 secured by means of the screws or 5 pins 0.

Upon the one end of the rod c I have arranged a plate e, provided with asleeve 6, a h0lding-sorew c and an adj usting-screw 6 Now when it isdesired to properly secure a 10 door-jamb in the opening in a wall allthat is necessary is to adjust all the plates at upon the screw-threadson the rods 0. Then by adjusting the side pieces a to the properdistance apart, according to the width of the door, I place thedoor-jamb about the properly-adjusted frame so that the edge f of thedoor-jamhfcomes in contact with all of the plates d. This having beenaccomplished, I next slip the upper plates 6 down against the edgef ofthe door-jamb, and then firmly screw the holding-screws 6 against therods c. To further insure perfect holding-contact of the surfaces f andf of the door-j amb with the plates d and e, respectively, theadjusting- 2 5 screws (1 and c are screwed down against the surfaces ofthe door-j amb, as will be clearly evident from Fig. 4. In this mannerthe sides of the door-jamb are arranged about my frame, and the threesides of the jamb 0 will be at right angles to each other. Then thesides of the door-jamb have thus been arranged about my setter, all thatis necessary is to place my setter and the j amb in the opening in thewall and secure the door- 5 jamb in position by means of nails or screwsand then releasing the several clampingscrews and the setter can beremoved from the door-jamb.

One of the side pieces ct can be provided with an opening or hole a",which is provided with a level g of any suitable construction, and saidside pieces can be further provided with a second level g, which can bearranged on a suitable bracket (L therefor, whereby 5 the door-jamb canbe set perfectly level and plumb, as Will be evident. As will be seenfrom Fig. 3, said door-jamb setter can also be adjustably arranged as toits length. The side pieces a. a are provided at or near their lower andfree ends with guides or ways h, in which are arranged the slides 7L,each having an adjusting-screw 7L3. side pieces a a can both belengthened, and are of great benefit for resting the setter upon thefloor when securing the door-jamb in position. Said guides 7b can alsobe provided with scales 7L2, if desirable.

Having thus described my invention, what I claim is- 1. A door-jambsetter consisting of side pieces connected with each other by crossarmsarranged in pairs and capable of adj ustment sidewise, and a scale onone of said arms, clamping-plates on said side pieces, and means foradjusting said clamping-plates to- In this manner the ward or from theedges of a door-jamb frame, substantially as and for the purposes setforth.
